The flag represents the golden eight-pointed star, the blazon of Robert
René Cavelier de La Salle. The azure blue and the waves call to mind the
St. Lawrence River as well as the Lachine Rapids and Canal. This flag was
adopted on December 7, 1969

The arms were granted on June 4 1992 by the Canadian Heraldic Authority.

I took a photo of this flag in 1999 in a Montreal Urban Community building.
I believe it is an older version than the one already on the website, which is
based on a recent photo. Notice that the blue is much lighter, and the stripes
much narrower. Several of the flags I saw in this building in 1999 seemed to
be older flags. In fact, Beaudoin reports a 2:3 narrow stripe
version with UN blue.
